Sonos Arc Ultra and Samsung TV - Dolby Atmos sound cutting out

Hello,

I had the same issue with my Sonos Arc. I thought it would be resolved with a new and pristine Sonos Arc Ultra. When gaming or watching uncompressed Dolby Atmos content, the sound cuts out for a split second every 20 minutes, almost on the minute. I have tried different HDMI 2.1 cables. Ultra High Speed cables. The sound is beautiful and flawless for 20 minutes at a time. So that’s about 3 moments of irritation every hour when gaming or watching movies.

Since the same issue has been here for 4 years, I’m starting to think it’s a Samsung issue. Is Sonos in contact with Samsung to resolve the issue together? I have tried about everything there is to try for the past 4 years. But I am open to suggestions.

Same Firestick and Sonos here, different TV and zero issues.

Looking at Samsung reports here I never considered buying one a good idea. My Sony does just fine.

It sounds frustrating! Since you've already tried different HDMI cables and other fixes, it might indeed be a compatibility issue between Sonos and Samsung. Unfortunately, I don't know if Sonos and Samsung are directly collaborating on a fix, but it's worth reaching out to both support teams for updates. In the meantime, you could try adjusting HDMI settings (e.g., turning off HDMI-CEC or switching to a different HDMI port), or using an external HDMI audio extractor as a workaround. Let me know if you need more suggestions!

I hopped on with support. They recommended a new hdmi cable from the TV eARC to Arc Ultra. I robbed the one from my Apple TV and so far I’ve had zero audio interruptions. This seems to have fixed it.

Equipment:

Sonos Arc Ultra, Sub 4, Era300 (x2)

Samsung S90D

Amazon 4k Max Firestick

What HDMI cable did you use?

Have you tried playing uncompressed Dolby Atmos TrueHD content?

I’ve been testing Dolby Atmos content via Netflix and Prime Video through the Firestick. I don’t THINK that’s uncompressed. The HDMI cable was the one that came with the Apple TV originally. This was an older gen ATV too (only 1080p).

Update after a week: I’ve had ZERO dropouts since changing the cable so that seems to have been the issue.

No dropouts with streaming services and compressed Dolby Atmos here either. But the uncompressed formats still dropout for a second every 20 minutes or so. From physical 4K UHD discs and from gaming on the PS5 Pro.
Sonos says this is s Sony PlayStation issue and they won’t do anything further to solve this.

The fact that you had this same issue with the original Arc and now the Arc Ultra leads me to believe this is more of a Samsung issue. More often than not, when someone reports audio dropouts from the Arc or Arc Ultra, it is from a Samsung TV owner.

So… the next TV I buy won’t be a Samsung, I guess…

I’ve got a similar issue. Brand new Arc Ultra, Sub4, Era 300s and a Samsung S90D. I’m using a fire stick 4k max to stream content. Turning Input Plus on or off makes no difference.

Are we screwed? Did I just dump thousands of dollars into a majorly flawed system?

I have the nearly exact set up as you except I have the Sub Gen 3. My previous Arc would experience the occasional drop out. When I first set up the Ultra it dropped out on me. I pulled the power cord out of the back of the S90D and Arc Ultra and left them unplugged for a few minutes. Plugged back in and powered up and haven’t had an issue since, over 60 days now.
Make sure you are using quality CERTIFIED HDMI cables. Amazon junk is often an issue. Quality cables aren’t cheap but they do make a difference.

Good HDMI cables are important, but you can get them for a very reasonable price. I use KabelDirekt cables and they work great. Don’t pay a fortune for HDMI cables. It isn’t necessary.
